I don't have one but I can tell you that I'll never buy one either. I recently got an STM32F4 Discovery for 12 dollars and it seems to be better in almost all ways. It's far cheaper, it has 192k of RAM, same amount of ROM, it runs at double the clock speed of the Due and the board has various things on it (a DAC, a mic, an accelerometor, and a usb host port). Every single pin on microcontroll er is broken out into male header pins. The only thing I can complain about is that the pins are broken out in a random order (they're not grouped into ports).

Am I right in thinking the Due is a replacement for the Mega in the same way as the Uno superseded the Duemilanove? Or is there a reason you'd buy the Mega still? I've not had reason to grab a mega nor Due but can see a place for the more capable boards even with cheaper dev boards around. The common IDE being the main one, especially for kids learning.

The limitation that stopped me running out and grabbing one is the inability to move to a standalone processor as easy as we can by developing on the Arduino with ATmega. Being able to use ATtiny or ATmega chippies simply removes the cost barrier from having a go at all manner of projects for me.

Having said all that, we already have a Raspberry Pi for every TV in the house...with a "need" for two more that we've identified...so whichever fits the task best works for me. It sure is exciting to have all this choice.Geoff

The Due has 2 DAC's and a USB host port just like the STM32F4. Note, for those people doing floating point, the STM32F4 does have hardware floating point, unlike the Due or Teensy 3.0 chips.
